[Mono-list] Suggestion: warning "member variable not initialized"

[Thong (Tum) Nguyen]

Hi Maurizio,

Readonly members are implicitly initialized (all memory is zeroed before
it is used) but since readonly members can't be set anywhere except for
in the initializer or constructor a warning is given.

The compiler will actually give an warning if you never initialize a
field but it won't give you an warning if you initialize it *somewhere*
(doesn't have to be the constructor).

So the C# semantics for all fields appear to be that a warning is given
if it is read *somewhere* but is never assigned a value *somewhere*.
